How do you convert decimal to binary? For example, the hexadecimal abc to binary is to convert them separately and together, a=1010, b=1011, c=1100, which is 101010111100 together.
How did the 128 turn into binary turn? Is it also opened and turned? Or do the numbers have a corresponding binary value?

The most common algorithm for decimal to binary is to divide it 2 continuously until the result is 0, and then connect each remainder from back to front, which is the result, such as your 128
128 / 2 = 64 — 0
64 / 2 = 32 — 0
32 / 2 = 16 — 0
16 / 2 = 8 — 0
8 / 2 = 4 — 0
4 / 2 =   2 — 0
2 / 2 = 1 — 0
1 / 2 = 0 — 1
The result is
10000000

12 (decimal) = 1100 (binary) Convert decimal integers to binary integers: Convert decimal integers to binary integers using " divide by 2, and reverse order " The specific method is: divide the decimal integer by 2, you can get a quotient and remainder; then use 2 to remove the quotient, and then get a quotient and remainder, and then proceed until the quotient is 0, and then use the first remainder as the binary number. The lower significant bit, the resulting remainder is used as the upper significant digit of the binary number, in order. Specific practice: 12/2=6 remaining 0 6/2=3 remaining 0 3/2=1 remaining 1 1/2=0 remaining 1 12 (decimal) = 1100 (binary)
